Visual Studio 2012中的Google测试 [英] Google Test in Visual Studio 2012

问题描述

我想开始进行单元测试。我下载了gtest的最新版本，并将其解压缩到 A：\gtest 按照指定的说明，我打开了gtest.sln。 Visual Studio只允许我打开sln如果我同意更新它。然后当我尝试构建我得到一堆错误：

I am trying to get started with unit testing. I downloaded the latest build of gtest, and extracted it to A:\gtest As the instructions specified, I opened gtest.sln. Visual studio only allows me to open the sln if I agree to update it. Then when I try to build I get a pile of errors:

我做错了什么，或者这是VS2012的问题？我不附加谷歌测试，我不反对使用一个不同的框架，如果它更好地与VS，我刚刚听到了很好的事情关于gtest。

Am I doing something wrong or is this an issue with VS2012? I am not attached to google test and am not opposed to using a different framework if it works better with VS, I had just heard very good things about gtest.

推荐答案

VC ++ 2012没有（永远不会）支持可变参数模板;因此，其标准库实现试图使用预处理器生成的重载和专门化来伪造它们。由于此博文注释，虚假变量模板参数的数量默认值到5–问题是gtest试图用多达10个模板参数来实例化 std :: tuple<> 。

VC++ 2012 does not (and will never) support variadic templates; consequently, its standard library implementation attempts to fake them using preprocessor-generated overloads and specializations. As this blog post notes, the number of faux variadic template parameters defaults to 5 – the problem is that gtest is trying to instantiate std::tuple<> with as many as 10 template arguments.

正如博客文章所述，您可以定义 _VARIADIC_MAX 宏项目范围内最多支持10个参数;您可能希望通过项目的预处理程序定义设置。

As the blog post goes on to mention, you can define the _VARIADIC_MAX macro project-wide to support up through 10 parameters; you'll probably want to do this by way of your project's preprocessor definitions setting.
